She so peaceful, yet causes fear
Him so bright and full of cheer
She rests the body, he wakes the soul
Him so light, she black as coal
Her with mole and tiny bright freckles
He covers us with tiny tear speckles
She hides us, he beams with pride
He her husband, she his bride
He in bright silk, her all in velvet
A yin-yang marriage as they tell it
Two lovers who meet but twice a day
When he must go, she need stay
Now I ask you, who are they?

Hint

One more thing you should know
She tucks us in, he bathes us in glow.Hide

I also thought SUN and MOON.
For 'penguinboy,' using poetic license, the MOON is black once a month, at NEW MOON, and the SUN and MOON meet twice a day because their LOCALES meet, once at dawn and again at dusk.
Lovely poem, lovely riddle.

Excellent job on your teaser. For those of you that are arguing for sun/moon...I thought of that answer too, but it is disqualified by the line "her with a mole and tiny bright freckles..." That makes it obvious that it is the night sky and not just the moon. Great job!!!

A very unique and poetic teaser. You put some thought into this one and it will get many to use their heads! The moon will not work because it will appear during the day time and/or sunlight hours, too! I enjoy the twist! Keep them coming.

Yayyyy I got a riddle! I got a riddle!! Yippeeee!!! That must mean it's a good one. Or maybe it's just because I'm an amateur astronomer and am often thinking of the night sky and celestial bodies as physical poetry...

Anyways, I was also thinking sun & moon at first, but a few more read-throughs and I decided to go with night & day because it seemed to "fit" better. Yippee, I say again!

Easy one
I don't know who deepsea is,but this was written by someone else. The last line was changed by deepsea. It originally read( for I am night,and he is day). I know it was written in the 18hds by a poet named Homer something.
